Description

Paddy-eliminator

The utility model belongs to farm machinery, specially refers to a kind of paddy-eliminator.

Present widely used paddy-eliminator, the main employing by hand feeds, and promptly dangerous, efficient is low again, or adopts mechanical grip, but poor reliability, the threshing and the work of cleaning are carried out step by step, single rollers running, and the working procedure complexity, threshing performance is unreliable.

The purpose of this utility model is to provide a kind of automatic feeding, threshing, screening, selection by winnowing, the disposable paddy-eliminator of finishing of pack.

The purpose of this utility model is achieved in that it is by body, guard shield, last cylinder, the feeding conveyer belt, seedling placing table, bottom roll, grass fork, cutting knife, the sieve eccentric wheel, fixing sieve, reciprocal sieve, the belt elevator wheel, elevator, the cylinder transmission case, last drum pulley, the conveyer belt gearbox, jackshaft, prime mover belt pulley, universal coupling shaft, bracing piece, the belt-driven wheel, the bottom roll belt pulley, the final election case, observe door, straw outlet, fan outlet, the blower fan inlet scoop, air register, the mouth of putting out cereal is formed, be fixed on the body on, be supported with cylinder and bottom roll in the step, the guard shield of whole coverings is housed on it, the body back, the final election case is housed under the guard shield and observes door, on body, the back of last cylinder is useful on bolt and drives the cylinder transmission case of going up cylinder, it is furnished with take-up device, in body the place ahead, become 4 ° 30 ' to arrange one vertically by 2 E type V belts, the conveyer belt support, spring, pulley concial disk, the feeding conveyer belt that nip drum is formed, be fixed with seedling placing table on the body, on the seedling placing table, straw outlet is equipped with in the body back, in seedling placing table one side, body the place ahead is fixed with U type bracing piece, the last drum pulley that is used for transfer conveyor belt power is installed in the seedling placing table bottom, bottom roll belt pulley and conveyer belt gearbox, the output of conveyer belt gearbox is equipped with two universal coupling shafts and cooperates with the belt-driven wheel, the bottom roll belt pulley links to each other with prime mover belt pulley, on the jackshaft of bottom roll, be fixed with induced-draught fan, elevator belt pulley and bottom roll belt pulley, be welded with uprooting weed fork and cutting knife on the jackshaft, fan outlet is housed on the induced-draught fan, blower fan inlet scoop and air register, the elevator belt pulley connects elevator, elevator is provided with the mouth of putting out cereal, one fixing sieve is arranged below the bottom roll, in fixing sieve bottom one rectangle is arranged, the reciprocal sieve of forming by support and screen cloth, it hangs on the body, links to each other with the sieve eccentric wheel with the bottom roll belt pulley.

The utility model is by the power source outputting power, drive bottom roll and the rotation of the draught fan impeller on same jackshaft through prime mover belt pulley, rotate by bottom roll belt pulley cylinder in the transmission of cylinder gearbox again, realize the twin-roll backward rotation, make rice threshing more most, efficient is higher.Bottom roll rotates simultaneously, through belt-driven wheel, conveyer belt gearbox, universal-joint spindle, drive the action of feeding conveyer belt, realize that paddy rice feeds automatically, because feeding conveyer belt and bottom roll have one 4 ° 30 ' angle, so in feeding process gradually, guaranteed the comprehensive engagement of spike of rice and cylinder, so do not had the grain of rice on the spike of rice because of contacting bad not taking off.When bottom roll rotates, through bottom roll belt pulley, the transmission of sieve eccentric wheel, drag reciprocal sieve and move back and forth, to remove the impurity in the grain of rice that fixing sieve leaks down.Because the back and forth motion of sieve impels the grain of rice to the motion of blower fan direction, when below, grain of rice process blower fan inlet scoop, impurity such as the careless end in the grain of rice promptly are sucked away eliminating, the grain of rice through selection by winnowing continues reach, falls among the funnel of elevator, finishes the pack task through top lander.

The utility model adopts said structure, have functions such as automatic feeding, threshing, screening, selection by winnowing, pack, the rice threshing process is once finished, save when manually cleaning merit in a large number, threshing is clean, it is clean to clean, efficient is high, rational in infrastructure, good manufacturability, easy and simple to handle are convenient to maintenance, and be safe and reliable.
